The Pythagorean theorem is a cornerstone of math that helps us find the missing side length of a right triangle. In a right triangle with sides A, B, and hypotenuse C, the theorem states that A² + B² = C². The hypotenuse is the longest side, opposite the right angle. Created by Sal Khan. Pythagorean Triples are a set of 3 numbers (with each number representing a side of the triangle) that are most commonly used for the Pythagoras theorem. Let us assume a to be the perpendicular, b to be the base and c to be the hypotenuse of …This relationship is useful because if two sides of a right triangle are known, the Pythagorean theorem can be used to determine the length of the third side. Referencing the above diagram, if. a = 3 and b = 4. the length of c can be determined as: c = √ a2 + b2 = √ 32+42 = √ 25 = 5.

You may also determine if a triangle is a right triangle by plugging its side lengths into the formula and solving. If it creates a solution, it is a right triangle. The formula is: a 2 + b 2 = c 2. In the “real world” one application might be to find ... A Right Triangle's Hypotenuse. The hypotenuse is the largest side in a right triangle and is always opposite the right angle. (Only right triangles have a hypotenuse ). The other two sides of the triangle, AC and CB are referred to as the 'legs'. In the triangle above, the hypotenuse is the side AB which is opposite the right angle, ∠C ∠ C . The converse of the Pythagorean Theorem is used to determine if a triangle is a right triangle. If we are given three side lengths we can plug them into the Pythagorean Theorem formula: If the square of the hypotenuse is equal to the sum of the square of the other two sides, then the triangle is a right triangle.Pythagorean theorem.
